If you have VCDS, check coolant temp and ambient temps when the car is dead cold and they should be close to each other. If you do not have VCDS, measure the resistance of both sensors. At any given temp, one should be close to double of the other. That's what I have observed on my sensor, which I believe to be good.

Im asking this because the temp has been floating around 160-175 on my dash gauge rather than the normal ~190. I've noticed it for a while and may just benefit from replacing it and seeing where to go from there. The car I am referring to is in my signature and for a little history i have no clue if or when the thermostat was last replaced.

I had a similar situation with my Golf, ALH vs AHU but systems function similarly. I replaced the temp sensor and the thermostat, problem all fixed. The 'stats have a reputation of becoming slow to respond over time and the sensors can be dodgy as well

Search for a Digital Corpus's thread that I posted in. I think I posted which color wires is which sensor.
